Tourists stare up into its void from within the hulking cathedral with mouths open in awe. But few realise that the great dome has another purpose, the results of which take place not up above them, but right down at their feet. The cupola is, in fact, one of the world&#8217;s most spectacular astronomical instruments. It&#8217;s an enormous <strong><span style=\"color: #000080\"><a style=\"color: #000080\" href=\"http:\/\/www.dictionary.com\/browse\/gnomon\">gnomone<\/a><\/span><\/strong>.<\/p>\n<p><iframe loading=\"lazy\" title=\"Gnomone: astronomia nella Cattedrale di Firenze\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/QGzmZHKLqBg?list=PL91A1C1F36227D6F1\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p style=\"text-align: justify\">Watch the video above with the Italian subtitles switched on.

Questo \u00e8 dovuto all\u2019effetto camera oscura che un piccolo foro fa quando proietta un&#8217;immagine, \u00e8 come succede nella camera oscura delle macchine fotografiche ecc. ecc.<\/strong><\/p>\n<p lang=\"it-IT\" style=\"text-align: justify\">The interesting thing is that what you see isn\u2019t a spot of light, it\u2019s actually, let\u2019s say, an image of the sun. This is due to the camera obscura effect which a small hole makes when it projects an image, it\u2019s what happens inside the dark room in the cameras, and so on.<\/p>\n<p lang=\"it-IT\" style=\"text-align: justify\"><strong>E quindi, alcune volte pu\u00f2 succedere che si riesce a vedere nell&#8217;immagine del sole anche delle macchie solari. Bisogna che siano molto grandi, per\u00f2 pu\u00f2 servire a osservare le macchie solari. Una cosa interessantissima per esempio \u00e8 che qui in duomo alcuni anni fa abbiamo osservato il transito di Venere sul disco solare, e avevamo circa 3.000 persone intorno a fare l\u2019osservazione assieme a noi!&#8221;<\/strong><\/p>\n<p lang=\"it-IT\" style=\"text-align: justify\">And so, sometimes it can happen that you manage to see sunspots in the image of the sun. They need to be very big, however it can be used to observe sunspots. A very interesting thing for example, is that a few years ago, here in the cathedral, we observed the passage of Venus across the solar disk, and we had about 3,000 people making this observation with us!&#8221;<\/p>\n<p lang=\"it-IT\" style=\"text-align: justify\"><a href=\"https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001.jpg\" aria-label=\"Solstizio 001\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-11899\"  alt=\"solstizio-001\" width=\"530\" height=\"482\" \/ src=\"https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001.jpg\" srcset=\"https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001.jpg 610w, https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001-350x318.jpg 350w\" sizes=\"auto, (max-width: 530px) 100vw, 530px\" \/><\/a><\/p>\n<p lang=\"it-IT\" style=\"text-align: justify\">If you want to observe the gnomone del Duomo di Firenze in action you&#8217;ll need to visit on these dates: <strong><span style=\"color: #000080\"><a style=\"color: #000080\" href=\"https:\/\/operaduomo.firenze.it\/blog\/posts\/il-passaggio-del-sole-dal-piu-grande-gnomone-del-mondo\" target=\"_blank\">Orario<\/a><\/span><\/strong><\/p>\n<p lang=\"it-IT\" style=\"text-align: justify\">A presto<\/p>\n","protected":false},"excerpt":{"rendered":"<img width=\"350\" height=\"318\" src=\"https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001-350x318.jpg\" class=\"attachment-post-thumbnail size-post-thumbnail wp-post-image tmp-hide-img\" alt=\"\" decoding=\"async\" loading=\"lazy\" srcset=\"https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001-350x318.jpg 350w, https:\/\/blogs.transparent.com\/italian\/wp-content\/uploads\/sites\/4\/2016\/06\/solstizio-001.jpg 610w\" sizes=\"auto, (max-width: 350px) 100vw, 350px\" \/><p>Il Duomo di Firenze, also known as La Chiesa Di Santa Maria Del Fiore, is one of the world&#8217;s most famous cathedrals.
